The plurality of sites 1 to 3 transmit an acknowledgment indicating that the execution information has been received to the management station 4, and the base station 4 confirms this (step 130). When the plurality of sites 1 to 3 transmit an acknowledge, the received execution information is stored in the memory unit 30 (step 140). The plurality of sites 1 to 3 receive the standard time every predetermined time and execute the time stored in the memory unit 30 (step 150). Further, the plurality of sites 1 to 3 read these time data, determine whether or not they match, and if they match, execute the execution information all at once and end (steps 160, 170, step). 220). If they do not match, the data is read each time the standard time data is executed, and this operation is repeated until they match (steps 150 and 160).

  The management station 4 retransmits the execution information to the site that has not received the acknowledge, and confirms the receipt of the acknowledge again (steps 180 and 190). When the acknowledge is confirmed, the process returns to step 140. If the acknowledgment cannot be confirmed, it is confirmed whether or not it has been retransmitted a predetermined number of times, and if it has been retransmitted a predetermined number of times, execution information cancellation is transmitted to the site and the process ends (steps 200 and 220). If it has not been retransmitted a predetermined number of times, the process returns to step 180 to repeat this operation.
